I’ve been seeing a bit on YouTube lately about OpenCloud:
I understand it’s the same folks as were behind Owncloud (the ones that didn’t spin off to Nextcloud, anyway), and rather than being LAMP-based, it’s Go-based, with flat-file data storage rather than a database. As a result, performance is said to be better (and performance certainly isn’t Nextcloud’s strong suit).
I haven’t played with it as yet–their preferred deployment is via one giant Compose stack (see opencloud/deployments/examples/opencloud_full at main · opencloud-eu/opencloud · GitHub - the .env file alone is 300 lines long) that wants to grab ports 80 and 443 for itself and thus doesn’t appear to play nicely with an existing reverse proxy setup. But it sounds like it may have some potential.
I have already asked myself this question, as OpenCloud is now being heavily promoted in Germany. With Peer Heinlein [1] [2] [3], the German godfather of mail servers, it has a supporter who lends the whole project weight and credibility.
When I think of secure email or private cloud storage, I don’t think of Proton, but rather Mailbox.org.
I created an app to test opencloud in NS8, it’s available from my repo. A valid certificate seems needed, a self-signed one didn’t work in my tests.
This is just opencloud, so for example keycloak or clamav from the compose stack are missing.
Login is admin:admin.
